their contents could be distinctly seen. Even on these a little i)ara- 

 site with a circular body and a large quadrate head, fringed around 

 with vibrating cilia, was distinctly noticed. Another parasite was 

 quite abundant upon the branchiEe, coursing up and down its sides 

 rapidly, with ample room and verge enough. I have met witli no 

 notice of anything of the kind, nor have I seen any figure like it. 

 Tlie nearest a|)proach is in Eticyc. Meth. pi. 12, Jig-. 44-46 {Trich- 

 oda p recce ps). It adhered by a small fringed disk, attached to wiiich 

 by a sliort stem was an expansion somewhat like a Calla leaf, with 

 Ions; incurved frino-es at the edges.

 shorter than oral ; branehiiie few, arranged in about five clusters on each side,

" Body small, slender, elongated, ])ale white, pellucid ; head with 

 a flake-white patch above in front of the oral tentacles. Dorsal ten- 

 tacles long, but shorter than the orals, slender, wrinkled trans- 

 versely, especially in contraction. They arise very near together, 

 and bear the prominent black eyes at their bases behind. Oral ten- 

 tacles very long and slender, smooth and gracefully curved. Papil- 

 lae or branchiaj rather few in number, long and slender, arranged 

 in about five clusters on each side, those in the second and third 

 clusters being longest. Foot narrow, pointed behind, and strongly 

 auricled in front. Colors : papillae bright crimson, tipped with a 

 ring of ()pai[ue white ; tentacles pale pink near their bases, with 

 their anterior halves white." (Sfiinpsoti.) Length, two fifths of 

 an inch. 



Found at Grand Manan, under stones at low-Avater mark. 



Resembles somewhat ^E. riifibranchialis, Johnst., but its foot is 

 not so long, nor its dorsal tentacles so tapering ; and its papilla? 

 arc fewer and longer. When disturbed, it rolls itself up so that its 

 branchia? i)roject in all directions like the rays of a star.
